A) RC
B) 2.5 RC
C) 1.2 RC
D) 6 RC
Correct Answer: C
Solution :
Time constant in R-C circuit is given by \[\operatorname{l} -RC\] Equivalent capacitance \[=\,\,\,\frac{2R\times 3R}{2R+3R}=\frac{6R}{5}\] \[\therefore \,\,\,\,\,l=\frac{6R}{5}\times C=\frac{6RC}{5}=1.2\,RC\]You need to login to perform this action.
